SPECIFICATION forming part of Letters Patent No. 642,171, dated January30, 1900.

Application filed November '7, 1899. Serial No. 736,178. (No model.)

To all whont it may concern:

Be it known that LMAXIMILIAN M.SUPPEs, of Elyria, in the county ofLorain and State of Ohio, have invented a new and useful Improvement inElevator-Buckets, of which the following is a full, clear, and exactdescription, reference being had to the accompanying drawings, whichform a part of this specification.

This invention relates to elevator-buckets of that class which areemployed in hoisting coal and other material to some elevated point andthen dumping the same. These buckets are frequently used where it isnecessary to raise them directly over the heads of workmen employedbelow, and as ordinarily constructed this is a dangerous practice byreason of the liability that lumps of coal or other material with whichthe buckets are loaded will fall over the upper edge of the bucket andstrike the workmen. The buckets being hastily loaded and oftentimesraised rapidly to a considerable height,accidents of this kind are veryliable to, and do in many instances, occur with serious or fatalresults.

The object of my invention is to provide means of simple character whichwill efiectually prevent accidents of this kind by making it impossiblefor the material loaded in the bucket to fall or spill over its edges;and with this end in view my invention consists in providing the bucketwith an extension telescopically engaging its upper portion and forminga guard-flange when the bucket is elevated, which extends considerablyabove the contents of the bucket.

My invention also consists in the novel construction and combination ofparts,all as hereinafter described, and pointed out in the appendedclaims, reference being bad to the accompanying drawings, in which-Figure l is a perspective view illustrating my invention; Fig. 2, avertical section through the upper portion of the same, and Fig. 3 is adetail view.

A designates the bucket proper,which may in general be of any well-knownor suitable construction. Around the upper edge of the bucket I place anexterior rim B, and over this rim 1 telescope an open-endcylinder-section C, which when in the raised position shown in Fig. 2forms an extension of the bucket-body. Within the lower end portion ofthis extension is an inwardly-projecting flange D,Whieh is adapted toengage with the under side of the rim B, as shown. Secured to thebucket-body are vertical guiding-ribs E, which are engaged by the flangeD. Extending diametrically across the upper portion of the extension 0is a bar F, to which is secured a loop or bail G for engagement with thehook of the hoist-chain.

As in practice the buckets are usually designed to carry a load ofseveral tons weight, the rim B, flange D, and bar F require to be strongand firmly secured to the parts which carry them. In the constructionillustrated said rim and flange are form ed by angle-pieces securelyriveted, respectively, to the bucket and extension.

The bar F is shown as composed of two channel-plates, between which theends of the loop or bail G are securely riveted, (see Fig.3,) and whichare secured at their ends by angleplates H. This construction is a verysimple and durable one; but it is not essential to my invention.

The operation will be readily understood. When the bucket is beingfilled, it rests on the ground or some other support, with thehoist-chain slack. The extension 0 slides down on the bucket-body bygravity to the position shown by the dotted lines in Fig. 2. As soon,however, as the bucket is raised the extension is lifted on the bucketuntilthe flange D engages the rim B. In this position it extendsconsiderably above the top of the contents of the bucket, although thelatter may be filled considerably above its upper edge and forms a guardwhich effectually prevents such contents from falling as the.

bucket is elevated.

I do not wish to limit myself to the particular construction which Ihave herein shown and described, as various changes may be made in themechanical details without departing from the spirit and scope of myinvention.

Having thus described myinvention, what I claim, and desire to protectby Letters Patent, is-

1. An elevator-bucket having a guard ex tension telescopically engagingits upper por tion, substantially as described.

2. An elevator-bucket having a guard extension telescopically engagingits upper portion, and means for elfecting a lifting engagement betweensaid extension and the bucket, substantially as described.

3. An elevator-bucket having a cylindric open-end guard telescopicallyengaging its upper portion and having alifting connection therewith, anda hoisting bail or loop on said guard, substantially as described.

i. An elevator-bucket, having a cylindric open-end guard telescoping itsupper portion, and means for connecting a hoist-chain to said extension,substantially as described.

5. The combination with an elevator-bucket having an exterior rim at itsupper portion,

of a cylindrical guard extension telescoping the upper portion of saidbucket and having an internal bottom flange for engagement with the saidrim, and means for connecting a hoist-chain to said extension,substantially as described.

6. The combination with an elevator-bucket and angle-plates secured toits upper portion and forming asurrounding rim, of a cylindric I openendguard extension telescoping the upper portion of said bucket, anangle-p1ate se cured within its lower portion for engagement with thesaid rim, and means for connecting a hoist-chain to the said extension,substantially as described.
